Faraday timeout error with omniauth (custom strategy)/doorkeeper - ruby-on-rails

Question

I'm currently following along with this railscast and for my specific situation am running into a Faraday timeout error on the callback from omniauth.
Currently I'm using a rails application as an API and backbone as a javascript front-end (on the same application)
I decided I wanted to lock down the API with OAuth and provided a custom strategy for Omniauth to access the API as a client as well as Doorkeeper to handle the authorization logic
module OmniAuth
module Strategies
class Twiddle < OmniAuth::Strategies::OAuth2
option :name, :twiddle
option :client_options, {
site: "http://localhost:3001",
authorize_path: "/oauth/authorize"
}
uid do
raw_info["id"]
end
info do
{
firstName: raw_info["firstName"],
lastName: raw_info["lastName"],
email: raw_info["email"]
}
end
def raw_info
#raw_info ||= access_token.get('/api/v1/user').parsed
end
end
end
end
I included the custom strategy like this:
require File.expand_path('lib/omniauth/strategies/twiddle', Rails.root)
Rails.application.config.middleware.use OmniAuth::Builder do
provider :twiddle, id, secret # Omitting the actual ones for obvious reasons
end
I am currently using these gems in my bundle
# OAuth
gem 'oauth2'
gem 'omniauth'
gem 'omniauth-oauth2'
gem 'omniauth-facebook'
gem 'doorkeeper'
Here is where I authenticate and attempt to retrive the proper access token (and also where I get stuck)
def loginParse
if ( user = User.authenticate( params[:email], params[:password] ) )
session[:user_id] = user.id
redirect_to '/auth/twiddle/'
else
render :controller => "authentication", :action => "loginIndex", :notice => "Incorrect credentials"
end
end
Here is the routing from the routes.rb
# Oauth urls
match '/auth/twiddle/callback', to: "authentication#connectAPI"
match "/auth/facebook/callback", to: "authentication#loginSocialMedia"
The application never is able to render the connectAPI action, getting COMPLETELY stuck at this point (given by the server logs)
User Load (0.4ms) SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 LIMIT 1
Doorkeeper::Application Load (0.2ms) SELECT `oauth_applications`.* FROM `oauth_applications` WHERE `oauth_applications`.`uid` = '' LIMIT 1

(1.4ms) COMMIT
Redirected to http://localhost:3001/auth/twiddle/callback?code=a
Completed 302 Found in 12ms (ActiveRecord: 3.7ms)
(twiddle) Callback phase initiated.
Many of the uids/important information have been omitted from the log.
Finally this error is given:
Faraday::Error::TimeoutError (Timeout::Error):
I hope I have been thorough in my explanation of this problem.
I don't know why exactly the application seems to be freezing at the callback initiated part of omniauth. I have tried updating bundler as a few other stackoverflow questions have pointed me to but it is not working.
Perhaps my understanding of OAuth2 is a bit murky.
If anyone can help me, I would greatly appreciate it

Answer 1

I'm not sure this applies to you been here was my scenario:
Problem
An app with data that our internal OAuth server wants
An OAuth server with little, to no data on it
We want to offload the authentication portion of App1 to App2 without moving data
Solution
App1 uses App2 as the Authentication server
App2 uses App1 for user data
Problem from this solution
Deadlock - App1 is waiting for an OAuth response from App2, but to complete
that response App2 must wait for a response from App1.
Final observation
In development mode on Rails (with WebBrick) you can't run multi-threaded, so the request
may never be allowed to complete.
My solution
My solution was to install puma and add to
config/environments/development.rb:
if ENV["THREADS"]
config.threadsafe!
end
Then when you start the server you'd do THREADS=1 rails s Puma to test your
OAuth stuff.
OR
Or your scenario is completely different and you're actually not communicating between
your services. Is your extra_info (like Github's /user) endpoint functioning on
the OAuth server? Is your callback actually doing anything?
I hope this helps!
